desc = "Overview:
vBulletin is prone to multiple cross-site scripting vulnerabilities
because it fails to sufficiently sanitize user-supplied data.

An attacker may leverage these issues to execute arbitrary script code
in the browser of an unsuspecting user in the context of the affected
site. This may allow the attacker to steal cookie-based authentication
credentials and to launch other attacks.

These issues affect vBulletin 4.0.2; other versions may also be
affected.
